Explanation:
A. Erosion of rock
D. Sediments are distributed by river to a new location
B. Particles settle out and form layers
E. Fossils form as living things are trapped in the layers
C. Humans analyze formations to determine the age of rock
The steps given are keys which ensures we understand how sediments form sequentially in basin of deposition. Coupled with this, we are shown a peep into the world of fossilization.
Any form of rock is first eroded before they are transported to their basins of deposition. In the basin, the particles settle out and form layers. The fossils trapped in them also settles out. The sediments gets compacted to sedimentary rocks. This sequence is therefore analyzed to determine the age of a rock.Based on the law of conservation of energy, which statement is correct?

Explanation:
The contact forces, such as friction or the push force, are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, intense repuesive forces are formed that objects move. We can see that in these forces the electrons are still attached to the material and only electoral repulsion is what creates the force.
In the previous explanation, it is valid for all types of material, the only change occurs due to the strength of the bond, in the case of materials with free electrons, such as metals, the forces are small, so the sliding occurs for small bourgeois
In insulating materials such as rubber where the electronons are tightly bound, closer proximity is needed to move the electrons from their equilibrium position.

The chart below shows the dates of eclipses in the years 2006 and 2007. What is the best explanation for the frequency of eclipses? The Moon's orbit is tilted relative to the plane of the Earth's orbit. About every six months, the Sun, Moon and Earth are aligned enough for a solar and a lunar eclipse to occur. The Earth and Moon orbit the Sun in opposite directions. When the Moon's orbit crosses the Earth's orbit, a lunar or solar eclipse will occur. A lunar or a solar eclipse occurs every time the Moon orbits the Earth. The Moon orbits the Earth four times a year. The atmospheric conditions that cause eclipses are only found at certain locations and times of year.
Answer:
It's A
As the Gizmo shows, the Moon orbits at an angle relative to the plane of Earth's orbit. Usually, the Moon is above or below the Earth when an eclipse could happen. Every six months or so, the Moon, Earth and Sun are lined up sufficiently to create a lunar and a solar eclipse.

Use the diagram showing the relationship among current,
resistance and voltage. Explain the relationship between
current and voltage;
voltage and resistance;
current and resistance.
Write your answer below
Answer:
There is no diagram in this question, however, the question can be answered based on general understanding.
1. current and voltage; direct relationship
2. current and resistance; inverse relationship
3. voltage and resistance; direct relationship
Explanation:
The relationship between current (I), resistance (R) and voltage (V) has been explained by Ohms in his law. In Ohms law, which states that the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.
This further means that if the voltage (V) increases, then the current (I) also increases and vice versa while if the resistance (R) is increased, the current (I) decreases and vice versa.
The equation represented by this law is:
V = IR or I = V/R or R = V/I
Likewise, the when the resistance is increased, the voltage increases and vice versa.
Therefore;
- Current (I) is directly proportional to the Voltage (V)
- Current (I) is inversely proportional to the Resistance (R)
- Voltage (V) is directly proportional to the Resistance (R)
Put them in order to smallest to largest: centimeter, femtometer, kilometer, light year, meter, nanometer
5. A pendulum is 0.25 m long. What is the frequency of its oscillations?
Answer:
I would say your answer is: The frequency of oscillations is 1 HZ { 1 cycle per second}.
The frequency of pendulum oscillations which is 0.25 m long is 1 HZ (1 cycle per second).
What is frequency?The quantity of waves leaving a spot in relation to time is known as its frequency. Hertz units are used to measure frequency. Humans with typical hearing abilities can hear frequencies between 20 Hz and 20 kHz. The frequency is defined mathematically as the time period divided by the factor of one. The number of rotations or vibrations that a body in periodic motion makes in a given amount of time.
A moving disturbance is referred to as a wave. The waves that must pass through a medium like air or water are referred to as mechanical waves. Other forms of waves, such as electromagnetic waves, can pass through both mediums and a vacuum.
Given:
The length of the pendulum, l = 0.25 m,

Answer:
Radioactive contamination
Explanation:
radioactive contamination is when radioactive atoms are present on somethingWhen an unwanted material that contains radioactive atoms is present in another material is known as Radioactive contamination.
What are radioactive atoms?The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive. Alpha, beta, and gamma decay are three of the most prevalent forms of decay, and they all entail the emission of one or more particles.
According to the statement, "For a given time, the number of nuclei of the elements existing at that moment is exactly proportional to the rate of radioactive decay of an atom." This may be expressed as, where N is the total number of nuclei, d N d t N.
When radioactive particles are deposited on, inside of, or around an individual or a business, nuclear radiation results. When radioactive materials are discharged into the environment, they have the potential to contaminate the air, water, surfaces, soil, plants, buildings, people, and animals.

The Sun light is reflected back by earth. On process of reflecting back the sunlight, the lower layer of troposphere absorbs the most sunlight and upper layer absorbs the least sunlight. So when We ascend to troposphere, we move towards the upper layer of troposphere where sunlight is least absorbed and is colder than lower layer where sunlight is most absorbed
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.

An object with a mass of 7kg gains the speed 26 meters per second after traveling the distance 2.8m. Calculate the resulting force that acts on it.
Answer:
F = 845 [N]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f} ^{2} =v_{o} ^{2} +2*a*x[/tex]
where:
Vf = final velocity = 26 [m/s]
Vo = initial velocity = 0
a = acceleration [m/s²]
x = distance = 2.8[m]
[tex]26^{2} = 0 +(2*a*2.8) \\5.6*a = 676\\a = 120.71[m/s^{2}][/tex]
Now we have to use Newton's second law which tells us that force is equal to the product of mass by acceleration.
ΣF = m*a
where:
F = force [N]
m = mass = 7 [kg]
a = acceleration = 120.71 [m/s²]
[tex]F = 7*120.71\\F = 845 [N][/tex]
